Overhead light fixtures and methods
An overhead light fixture includes a driver assembly and a light-emitting assembly. The driver assembly includes a driver and a housing. The light-emitting assembly is operably connected to the driver and configured for downward emission of light from a light source of the light-emitting assembly. The light-emitting assembly is detachably secured to the driver assembly. The light fixture is configured to be mounted to a canopy sheet of an overhead canopy, with the driver assembly disposed above the canopy sheet and the light-emitting assembly disposed below the canopy sheet. The driver assembly is optionally configured so that, when the light-emitting assembly is detached from the driver assembly, the driver is removable downwardly through the base portion. A bezel is optionally disposed around a lens of the light-emitting assembly, for aesthetic reasons and/or for controlling a degree of lateral emission of light from the light fixture.
1. An overhead light fixture for mounting to a canopy, comprising:
a driver assembly, comprising:
a housing having a base portion and a sleeve portion extending at a non-orthogonal angle therefrom; and
a driver detachably mounted in the sleeve portion such that the driver is removable through the base portion; and
a light-emitting assembly detachably coupled to the base portion, the light-emitting assembly comprising a light source operably connected to the driver and configured to emit light away from the base portion.
2. The overhead light fixture of claim 1 , further comprising a mounting bracket configured to be secured to the canopy, wherein the mounting bracket has a pass-through opening, and the light-emitting assembly and the driver assembly are secured to opposing sides of the mounting bracket.
3. The overhead light fixture of claim 2 , wherein the pass-through opening is sized not more than 30% a size of the light-emitting assembly.
4. The overhead lighting fixture of claim 1 , wherein the non-orthogonal angle is greater than 0° so that the sleeve portion is angled above horizontal relative to the base portion.
5. The overhead light fixture of claim 4 , wherein the non-orthogonal angle is in the range of 30° to 60° relative to the base portion.
6. The overhead light fixture of claim 1 , wherein the sleeve portion extends linearly from the base portion.
7. The overhead light fixture of claim 1 , wherein the lighting fixture is configured such that the light-emitting assembly can be secured to the driver assembly at any one of a plurality of relative rotational orientations.
8. The overhead light fixture of claim 1 , further comprising a bezel disposed peripherally about the light-emitting assembly.
9. The overhead light fixture of claim 1 , wherein:
the driver assembly further comprises a tray assembly comprising a driver tray secured to the driver; and
the driver tray is secured in the sleeve portion such that the driver is protected by the sleeve portion.
10. An overhead light fixture for mounting to a canopy, comprising:
a driver assembly, comprising:
a housing having a base portion and a sleeve portion extending at a non-orthogonal angle therefrom; and
a driver detachably mounted in the sleeve portion;
a light-emitting assembly detachably coupled to the base portion, the light-emitting assembly comprising a light source operably connected to the driver and configured to emit light away from the base portion; and
a mounting bracket configured to be secured to the canopy, the mounting bracket having a pass-through opening, wherein the light-emitting assembly and the driver assembly are secured to opposing sides of the mounting bracket.
11. The overhead light fixture of claim 10 , wherein the mounting bracket comprises a plurality of arms extending from a central region.
12. The overhead light fixture of claim 11 , wherein the pass-through opening is disposed in the central region.
13. The overhead light fixture of claim 10 , wherein the driver is detachably mounted in the sleeve portion such that the driver is removable through the base portion.
14. The overhead light fixture of claim 13 , wherein the driver is removable through the base portion when the light-emitting assembly is detached from the base portion.
15. An overhead light fixture for mounting to a canopy, comprising:
a driver assembly, comprising:
a housing having a base portion and a sleeve portion extending therefrom; and
a driver mounted in the sleeve portion such that the driver is removable through the base portion;
a light-emitting assembly disposed below the driver assembly and detachably secured to the base portion of the driver assembly, the light-emitting assembly having a lens configured for downward and lateral emission of light from a light source of the light-emitting assembly;
a first bezel configured to be disposed around the lens and block a first portion of light laterally emitted from the lens when disposed around the lens; and
a second bezel configured to be disposed around the lens and block a second portion of light laterally emitted from the lens greater than the first portion of light when disposed around the lens;
wherein at least one of the first bezel or the second bezel controls a degree of the lateral emission of the light from the light fixture.
16. The overhead light fixture of claim 15 , wherein:
the lens has a lower face disposed vertically downward farthest from the driver assembly;
a height of the first bezel is such that the first bezel, in side view, forms a first vertical gap with the lower face when disposed around the lens; and
a height of the second bezel is such that, in side view, the second bezel forms a second vertical gap with, or is flush with, the lower face when disposed around the lens; the second vertical gap smaller than the first vertical gap.
17. The overhead light fixture of claim 15 , wherein the sleeve portion extends from the base portion at a non-orthogonal angle.
18. The overhead light fixture of claim 15 , wherein the driver is removable through the base portion when the light-emitting assembly is detached from the base portion.
